Ok minus water changes, snails, lawn mower blenny, hermits, and cutting back on my lighting any ideas on how to rid of hair alage its on the back of my tank. i know i can manually remove it as well. I feed the tank once a day, lights on for 8 hrs. any other ideas i can't kill my lights for days due to corals. would it be safe to cut the lights back to 4hrs a day its t-5's total of 432watts. and see how that goes, or would that stress the corals too much. my parameters are 0/0/0
